Beit known that I, CONSTANTINE LEE .STRAUB, a citizen-of the UnitedStates, residing at Milwaukee, in. the county of Milwaukee-and State ofWisconsin, have invented certain new and useful Improvements in SuetionGas-Producers, of which the following-is a specification.

, Thisjinvention relates to a suction gas "producer, of that kind inwhich air and wa-; ter vapor or steam are drawn into the body 'of-fueland ther'esulting gas is drawn from he producer or generator by a gasengine or other means.

The object of my invention is to provide for generating gas of a moreuniform qualitv or thermal va-lue and supplying the same in a moreuniform stream or 'flow from the producer or generator to a gas engineor other place: of use, than has heretofore been attainable with suchproducers.

Another object of my invention isto provide for effectivelyandeeonomieally heatingair, spraying or' vaporizing water, inin-' jglingthespray or vapor with hot air and instantly converting it into steam ina theater by means of-waste heat o f the pro- 1 e1;i and the outfiowinghot gas, and sup such hot air and steam in a substan tial'ljyunifornifiow'to the body of incan- ..de scent fuel in the producer forgenerating as.

The gas producer A is constructed with the usual riveted plate-ironshell and fire brick lining upon a concrete foundation X,- and isprovided near the base with a fire door a above the grate and with anash pit door a" opening'into the ash pit a". The

ash pit is preferably provided-with a brick floor a,'but without a-bricklining, as shown. An iron top plate a is riveted to the ,outer shell andextends over the shell or casing of the flash boiler or super-heater Cup to'the opening for the'fuel hopper. A filling of. fire sand is lacedbet-ween t-heshelland the fire brick lining, as'shown in Fig. 2-. Thetop of the ash pit is made of an annular cast-iron plate or hearth B,supported onbrackets riveted to the shelland having a large centralopening, into which is 'setrthe rocking or shaking grate B In a hangerZ) projecting from the hearth B and a suitable hearing in the shell issupported a rock shaft 12, to the inner endof which is connected a lever7/ which con- ,nects with the shaking grate. To the outer end ofshaft 1) is connected a hand lever b for operating the grate. w

" The inwardly projecting-annular hearth 13 forms a: contracted grateopening and prevents air or air and steam from passing up along the sidewalls of the producer; it

also serves as a support for the re-heater chambers Dland brick lininThere-heater D while of notable utility,

extending down from the flash-boiler. By this arrangement the commingledhot air and steam which enter through pipe 0" are caused to passaroundthrough the re-heater' chambers and become superheated before escapinginto the ash pit and passing thence up intothe body of fuel.

At the top of the brick lining is c011- vstructed a comparatively thinwall 6, Figs. 2 and 4, forming an annular gas outlet flue E, havingan"inlet opening 6 opposite the connection of the gas take-ofi' pipe H.Adjacent to this fine E, are riveted to the outer iron shell six castiron brackets (13 suitably spaced apart for supporting the annularflash-boiler or super-heater G. The flashboiler is supported on the castiron brackets, and in turn supports the fuel feed-hopper F, on theflash-boiler or super-heater C is the top closure sheet plate a soconstructed and attached asto prevent the admission'of air at the top ofthe generator. This'is' an economical and simplified construction as itdoes away with an extra cast-iron cover, heretofore required, andreduces the cost of construction. The flash-boiler is preferablycomposed of two segmental half boxes C, C arranged over the annulargas-outlet flue E and projecting inwardly from the Wall 6 partly over thefuel-chamber E as shown in Fig. 2. 'These super-heater boxes have castwith them the vertical or downwardly flaring poke-holes 0, arranged in aas indicated inFigs. 2 and 3. These superheater boxes C, C are alsoprovided with Ill inner upwardly projecting flanges 0 which serve as abearing forthe outwardly projecting flanges of the discharge spout F ofthe fuel hopper. The top 'of the producer is made tight by a wroughtiron plate a which is secured to the angle iron ring at the top edgeofthe shell and is inserted between the interior flange 0 of the boxes andthe flange 7' of the discharge spout and is also made tight around theoke-holes 0.

'The space between the top 0 the superheater boxes and the cover-plateat is filled with a packing e" of asbestosormineral Wool to preventradiation from the flashboiler. The poke-holes 0 extending through theflash-boiler serve as braces and increase the heating surface thereof.-

By means of the construction shown and above described the hot gaspassingfrom the body offuel circulates around, first undcr'theinwardly-projecting part of superli6z1it1" C, thence through-port e andback around under the outer part thereof, thereby high1y heatingchamber'C before escaping to the take-01f pipe H. j

\Vhen the superheater is made of two segmental boxes a special form ofell inlet pipe J is provided, being so constructed as to connect withthe interior of both boxes at their adjacent ends. The super-heater isalso made as a single annular chamber C 'Wlth which. is connected theair and'vapor supply pipe J with valve 3', shown in Fig.

The fuel feed-hopper is composed of a body portion F, an upper charger Fand a lower contracted discharge spout F projecting down centrallythrough the super- J heater into the fuel chamber, as shown m- Fig. 2.The discharge spout'F is. provided at'the top with'an annular flange fwhich rests upon the topv plate a on the flange c' of the'superheaterchamber C. The charger F is mounted on the body portion F and 15.

provided with-a tight fitting cover 1'', a inorable bottom plate f", andwith-.a' locking,

device arran ed to lock the closed hot- 7 D I 1 tom plate when the coveris open and to c11- gageand lock the closed cover when the botv tomplate is open and discharging fuel into the hopper.

A gas outlet pipe H connects with the annular gas flue E and with aspeciallycom structed purge-valve I. with which is connected the gastake-off pipe H extending down through the pre-lieater shell K, which issupported upon-the concrete foundation X The lower end of pipe H isconnected with a cross pipe or four way coupling H, which connects bypipe H with the base of the wet scrubber P; One branch of the coupling Hextends through the shell of heater K and is closed by a removablecoverplate 71, and another branch '71" projects down to the foundation,and'i's, adapted to receive and the superheater- C.
